' Application July 18, 1944, Serial No. 545,456

(Cl. 72 ss) 1 Claim. 1

My invention relates to a building wall made of cement or like brick and the bricks for constructing said wall and the objects of my invention are:

First, to provide a building wall made of particularly constructed brick whereby the brick are bonded in their relation to each other by interlocking plaster bonds;

Second, to provide a building wall of this class made of special brick each provided with a plurality of dove-tailed interlocking grooves for receiving the plaster used between the bricks;

Third, to provide a brick wall of this class, the separate bricks of which are so shaped that they are provided with inverted V-shaped spaces intermediate the sides of the bricks when positioned in the wall, as well as plaster interlocked with each other;

Fourth, to provide a building wall of this class in which each of the bricks is provided on all of its sides with dove-tailed plaster receiving grooves arranged to plaster interlock with conforming positioned grooves with adjacent bricks;

Fifth, to provide a building wall of this class in which the separate bricks are easy to lay in position in proper location one with the other;

Sixth, to provide a novel building wall brick; and

Seventh, to provide a building wall of this class which is very simple and economical to construct, very durable and which will not readily deteriorate.

With these and other objects in view as will appear hereinafter, my invention consists of certain novel features of construction, combination and arrangement of parts and portions as will be hereinafter described in detail and particularly set forth in the appended claim, reference being had to the accompanying drawings and to the characters of reference thereon which form a part of this application in which:

Figure 1 is an end elevational view of one of my building brick; Fig. 2 is a fragmentary sectional view of a wall taken from the line 22 of Fig. 3 showing plaster on one side of the wall and showing fragmentary portions of similar bricks showing a double brick wall; Fig. 3 is a fragmentary side elevational view of the wall with the plaster omitted on the sides and Fig. 4 is a top or plan view of two bricks shown end to end in the wall.

Similar characters of reference refer to similar parts and portions throughout the several views of the drawings.

The building brick l is preferably made of cement, concrete or similar material and is generally substantially the size and shape of conventional brick but may be considerably larger in substantially the same proportion, if desired. It is provided on its normally upper side with an inverted V-shaped ridge portion la, the sides of which are substantially at a right angle to each other. It is also provided in its normally lower side with a similar V-shaped recess lb extending the full length of the brick. Each of the bricks is also provided with dove-tailed grooves, lo and l d, in its upper side On opposite sides of the ridge Ia and intermediate said ridge and the side of the brick. It is also provided with similar dove-tailed grooves le and I f at the middle of the opposed side walls of the brick. It is also provided with similar dove-tailed grooves lo and lb in the lower side of the brick intermediate the sides of the recess lb and the side of the brick, all as shown best in Fig. l of the drawings. These bricks are laid in lapped relation to each other in the wall, as shown in Fig. 3 of the drawings, with the conventional thickness of plaster layer between the brick, as indicated by the letter P. The bricks thus laid are arranged so that the dove-tailed grooves are in opposed adjacent relation with similar dovetailed grooves in the adjacent bricks, whether in superposed relation or side by side, as shown best in Fig. 2 of the drawings, thus providing for the plaster P to fill the opposed dove-tailed grooves, as shown in Fig. 2, providing interlocked relation of the bricks by the plaster layers.

The side of the wall made of these bricks, whether the inside or the outside, may be covered with plaster, as shown at P in which this side wall plaster interlocks with the brick by means of the dove-tailed slots therein, as shown best in Fig. 2 of the drawings.

In case the wall is a double brick wall, the plaster P forms an interlocking relation in the same manner for interlocking the sides of the brick with each other, as shown in Fig. 2.

It will be noted that the plaster P spaces the brick from each other when in superposed relation to each other leaving an inverted V-shaped opening 0 forming an air space in the wall without perforating the brick.

It will be here noted that the bricks are locked relatively to each other by the plaster bond, the plaster entering the dove-tailed grooves in the brick in opposed relation to each other, thus uniting the bricks against separation as well as lateral movement and providing an efiicient plaster bond in connection with the bricks in their relation to each other.

Though I have shown and described a particular construction, combination and arrangement of parts and portions, and a certain special brick construction, I do not wishto be limited to this particular wall construction, nor to the particular brick construction, but desire to include in the scope of my invention, the construction combination and arrangementsubstantialhz as set fortlr: in the appended claim.

Having thus described my invention, what I;

claim as new and desire to secure by Letters Patent is:

In a building wall, a plurality of solid. bricks laid in courses one uponanother with mortar spacing the bricks of adjacent courses'eaclrbricw having laterally spaced dove-tailed grooves-v extending longitudinally of its upper and lower surfaces, a rib of V-shaped cross section projecttween. the spaced groovesof: the lower surface;

ing-upwardly from the-upper'surface ofsaidbrick a distance greater than one-half the vertical" thickness of said brick and" extending; longitudinallyfrom end to end of'the, brick between the; spaced grooves in the uppensurface; andia recessof: V-shaped cross section. in. the lower surface of; sai d brick; extendinglongitudi'n'ally' thereof beand housing ,the:r-ibof'a brick in thecourse' below;

thesurfacesof the-recessbeing,spacedfrom the. 30

surfaces of the rib therebelow, and forming a cavity and the mortar extending laterally from the base of the rib between the bricks of adjacent courses and into the opposing spaced grooves for keying the bricks together.
